![]() ![]() See also this answer, which is very similar, and suggests postfile and statsby.įinally, check ssc describe estout, if your goal is to output regression tables. ![]() geodist can also calculate great-circle distances using the haversine formula. By default, geodist implements Vincentys (1975) formula to calculate distances on a reference ellipsoid. As far as I know, there's no way to apply either method to an actual physical route to adjust for curvature. , TwoRegression, Develop and Apply Two-Regression Algorithms. Both methods can be used in Stata using geodist from ssc (which has a great help file with references). See help extended_fcn if you're not familiar with them. geodist calculates geographical distances by measuring the length of the shortest path between two points along the surface of a mathematical model of the earth. , corx, Create and Format Correlation Matrices. Replace rownames = "`:word `i' of `rownames''" in `i'Įxtended macro functions are used. Local newnames : subinstr local names "_cons" "cons", word get original column names of matrix and substitute out _cons get original row names of matrix (and row count) E-Mail z/OS CICS Exception Reports in Plain Text Format Using DATA NULL and MXG. exporters and investors, in the form of subsidies or tax. package comes with two example datasets (Gravitynozeros and. data we compiled a dataset in Stata format with the border-sharing dyad-year as. compiled the two new cross-country datasets widely used for the applications of the toolkit. Gravity models in their naive form trace back to the work of Tinbergen (1962) and. Although Stata variable names can usually start with an underscore _, 11.3 Naming conventions explains that _cons is a reserved name, and they can't be used as variable names. general result shows that the longer the border between two states. ![]()
